u Si i,... ZET 8/ oo compartment of the air chamber and is provided witha eoi'itrolling valve 9 having an actuating lever 9, it being understoodthat the Huid supply pipe 3 extends to a scrubber mechanism, not shown.Directly under the mouth of the fluid-pipe 9 a V- shaped drip-pan 10 isprovided, in the form of a ring, the saine being secured, as shown,

which point they are supported by a ring.

11', the same being, in turn, supported by brackets 12 that are securedto the jacket 1. The ring 11 also carries an inwardly dared metallicfire-pot hopper 13, which is preferably formed in detachable sectionsand under this tire-pot is arranged a suitable rocking grate 14, thesame being disposed in the ash-pit section of the jacket, which ashpitsection extends from the ring 11 to the bottom of .said jacket.

The mouth of a conductor pipe 15 is arranged to communicate With the airstorage compartment c of the chamber, which pipe is in the form of anelbow having a horizontal section 15 that extends into the ashpit,terminating With an upwardly discharging mouth in axial alinement withthe fuelj pot and directly under the grate. Extending Within thevertical leg 15 of the conductor pipe is a humidistat 16 provided with alever mechanism 16', which mechanism is con-l nected to the actuatinglever 9 of the steam supply valve 9 by; a rod 17, whereby the valve 9 iscontrolled through the action of said humidistat.

ln the 'operation it is obvious that air forced through the nipple 8,Will pass through the apertures of the first ring 8 and be slightlyretarded prior to being dischargedv below the second ring S". Incidentalto the air being momentarily retarded Within the mixing compartment,watenis admitted thereto, whereby the air will absorb the vproper degreeof humidity to effect perfect combustion. The humidied air is thereaftercaused to travel through the conductor pipe and be discharged under thefuel pot. Should' the humidity increase over a predetermined degree, thehumidist-at Will act upon its lever mechanism 16 and thus cut ed orrestrict the supply of Water by means' of its Valve connection to theWater pipe or` vice versa. It is obvious that, owing to the fact thatthe gas-receiving throat projects downwardly and centrally of the fuelpot,it will cause a large percentage of the gas to be pocketed at thehead end of the pot, which gas must return and be discharged in 'an evenflow into the mouth o f the throat, whereby it is collected and thendelivered tothe point of storage or consumption and, furthermore, that,owing to the fact that the water jacketed head of the producer being incommunication with a chamber formed between the double walls of thercceiving throat, the same is held at a sulficiently low temperature toprevent burning out-mud, furthermore, this increased area of the waterjacket also serves to correspondingl y increase the capacity of saidjacket as a water heater for supplying the humidifier.

Particularl attention'is called tothe fact that the chamber about thecasing is divided by the perforated rings S', 8, t` :'st into an uppercompartment for receiving the supply of air the volume of which isretarded or choked in its flow to the mixing compartment .7; thercbeloivas it iiows through the ring apertures. Hence the slightly con'- tinedair in the upper compartment Will be distributed equally about thecasing and be discharged in a uniform sheet to the mixing` compartmenttherebelovv AWhere it receives the humidifying Huid. The humidiied airin the mixing` compartment is then slightly retarded to permit perfecthumidication and thereafter the evenly humidified air is then dischargedthrough the apertures in the lower ring 8 into the storage compartmentc, from which storage compartment it is drawn olf and delivered underthe grate. This method .of interrupting the air and successively causingit to travel from one compartment to the other materially increases theefficiency of the apparatus and ,insures a uniform mixture of properlyhumidiied air being supplied to the grate for producing combustion, thuseliminating all tendency' of air being discharged only partiallytreated.
